By Ed Sobey. More than 30 demonstrations of 16 model craft are outlined here in illustrated, reproducible how-to handouts that list materials, describe procedures, and explain scientific principles. A soda-can engine, balloon-powered rockets and rocket cars, air-jet propulsion, pump rockets, and "implosions and explosions even your mother will like" are all on the menu in a book that aims to "convince the kids that they are rocket scientists and the rocket scientists that they are kids." Grades 4–9. Index. Glossary. Suggested resources. 8½" x 11". 106 pages.
